Answer:
The answer to your question is below
Step-by-step explanation:
pH definition
pH = - log [H⁺]
a) For pH = 2.4, solution A
2.4 = -log[H⁺]
[H⁺] = antilog⁻².⁴
[H⁺] = 0.00398
For pH = 9.4, solution B
[H⁺] = antilog⁻⁹.⁴
[H⁺] = 3.98 x 10⁻¹⁰
b) Divide hydrogen-ion concentration of solution A by hydrogen-ion concentration of solution B.
0.00398 / 3.98 x 10⁻¹⁰
10000000 times
c) By 7, because 7 is the number of zeros
Answer: n = 4
Step-by-step explanation:
-6(-2n + 4) = 24 (divide both sides by -6)
-2n + 4 = -4 (subtract 4 from both sides)
-2n = -8 (divide by -2 on both sides)
n = 4
Answer:
B. 6
